Operator’s manual | E1250 | 5200016691 | 11/2020 | [us]

3.3 Residual Risks

This machine has been designed and built in accordance with the latest

global safety standards. It has been carefully engineered to eliminate haz-

ards as far as practicable and to increase operator safety through protective

guards and labeling.

taken. They are called residual risks. On this machine, they may include ex-

posure to:

• Heat, noise, exhaust, and carbon monoxide from the engine

• Heat, noise, and exhaust from the engine or hydronic heater

• Burns from the HTF or radiant heat from the hoses

• Fire hazards from improper refueling techniques

• Tripping hazards from the hoses

• Fire hazards from improper refueling techniques

• Fuel and its fumes

• Electric shock and arc flash

• Personal injury from improper lifting the trailer tongue

• Typical hazards related to towing a trailer on roads and highways

To protect yourself and others, make sure you thoroughly read and under-

stand the safety information presented in this manual before operating the

machine.

Operator’s manual | E1250 | 5200016691 | 11/2020 | [us]

4.2 Safety Guidelines for Operating the Machine

Operator and service training, knowledge, and qualifications

Before operating, maintaining, or servicing the machine:

• Read and understand the operating instructions contained in all manuals

delivered with the machine.

• Always keep this Operator's Manual and other manuals that accompany

the machine stored with the machine and available for use. Immediately

replace an incomplete or illegible Operator's Manual.

• Familiarize yourself with the location and proper use of all controls and

safety devices.

• Know the rules for the job site.

• Contact Wacker Neuson for additional training if necessary.

When operating this machine:

• Do not allow improperly trained people to operate the machine.

• People operating the machine must be familiar with the potential risks

and hazards associated with it.

• Follow legal and other mandatory regulations relevant to accident pre-

vention and environmental protection. These may include handling haz-

ardous substances, issuing and/or wearing personal protective equip-

ment, or obeying traffic regulations.

The machine must not be accessed or operated by:

• Children

• People impaired by alcohol, drugs, or prescription drugs

Application area

Be aware of the application area.

• Keep unauthorized personnel, children, and pets away from the ma-

chine.

• Remain aware of changing positions and the movement of other equip-

ment and personnel in the application area/job site.

• Identify whether special hazards exist in the application area, such as

toxic gases or unstable ground conditions, and take appropriate action to

eliminate the special hazards before using the machine.

• Do not operate the machine in areas that contain flammable objects, fu-

els, or products that produce flammable vapors.

• Keep the area around the muffler free of debris such as leaves, paper,

cartons, etc. A hot muffler could ignite the debris and start a fire.

when machine is full of vapor, or when the combustion chamber is very

hot.

• Do not tamper with the unit or controls—call your service personnel.

• Should overheating occur or the gas supply fails to shut off, do not turn

off or disconnect the electrical supply to the pump. Instead, shut off the

gas supply at a location external to the machine.

• Do not use this heat exchanger if any part has been under water. Imme-

diately call a qualified service technician to inspect the heat exchanger

and to replace any part of the control system and any gas control which

Safety Guidelines for Operating Combustion Burners 4.4

17

[us] | 11/2020 | 5200016691 | E1250 | Operator’s manual

4.4 Safety Guidelines for Operating Combustion Burners

When using the machine:

• Make sure you have proper certification or licensing required by the lo-

cality, state, or province in which the machine is being installed to con-

nect natural gas or LP.

• Clean up any spilled fuel immediately.

DANGER

Carbon monoxide hazard

Using this machine indoors can kill you in minutes. Exhaust gas contains

carbon monoxide (CO). This is a deadly poison you cannot see or smell. If

you can smell the exhaust, you are breathing CO. Even if you cannot smell

the exhaust, you could still be breathing CO.

► Never operate the machine inside an enclosed area, such as a home,

tunnel, or garage unless it is vented properly

► Only use the machine outside and far away from windows, doors, and

vents. These openings can pull in exhaust gas.

► Always use a battery-powered or battery-backup CO alarm in nearby

structures. Even when you use the machine correctly, CO may leak into

nearby structures.

► If you start to feel sick, dizzy, or weak after the machine has been run-

ning, move to fresh air IMMEDIATELY. See a doctor. You could have

carbon monoxide poisoning.

When using the machine:

• Do not fill or drain the fuel tank near an open flame, while smoking, or

while the machine is running.

• Do not smoke when refueling the machine.

• Do not smoke when connecting natural gas or LP.

• Do not attempt to start the burner when excess oil has accumulated,

when the unit is full of vapors, or when the combustion chamber is very

hot.

Note: Some machines may not be capable of supporting natural gas or LP.

Please see the burner manufacturer’s literature for more information.

4.5 Safety Guidelines for Operating Generators

DANGER

Carbon monoxide hazard

Using a generator indoors can kill you in minutes. Generator exhaust con-

tains carbon monoxide (CO). This is a poison you cannot see or smell. If you

can smell the generator exhaust, you are breathing CO. But even if you can-

not smell the exhaust, you could still be breathing CO.

WARNING

Electrocution hazard

Generators present special hazards during operation and servicing. These

include the risk of electrocution or severe electrical shock. Failure to follow

the safety information below can result in severe injury or death.

► Read and follow the safety instructions in this Operator’s Manual.

► Contact the generator manufacturer for additional information regarding

the generator.

WARNING

Internal combustion engines present special hazards during operation

and fueling.

Failure to follow the warnings and safety instructions could result in severe

injury or death.

► Read and follow the safety instructions in this Operator’s Manual.

► Contact the generator manufacturer for additional information regarding

the generator.

WARNING

Most used oil contains small amounts of materials that can cause cancer

and other health problems if inhaled, ingested, or left in contact with skin for

prolonged periods of time.

► Take steps to avoid inhaling or ingesting used engine oil.

► Wash skin thoroughly after exposure to used engine oil.

This machine is built with user safety in mind; however, like any electrical de-

vice it can present serious hazards if improperly operated and serviced. Fol-

low instructions carefully. Should questions arise during operation or service

of this equipment, contact your Wacker Neuson dealer.

General precautions

• Keep a multi-class, type ABC or equivalent fire extinguisher at hand

when using the generator. Refer to NFPA No. 10 for further information

regarding fire extinguishers.

• Do not use evaporative starting fluids. They are highly explosive.

• Do not store items such as excess oil, oil rags, or tools within the gener-

ator compartment. Items stored within the generator compartment are a

fire hazard and can restrict cooling air.

Refueling safety

When adding fuel to the fuel tank:

• Do not refuel a hot or running engine.

• Keep sparks, flames, electrical arcs, and other sources of ignition far

away from the generator.

• Refill the fuel tank only in a well-ventilated area.

• Reinstall the fuel tank cap after refueling.

• Do not smoke.

Maintenance safety

• Only a trained technician should attempt to repair the generator.

• Test procedures which require that the generator be running must be

performed using extreme caution.

• Make sure clothing and shoes are dry, stand on a dry wooden platform

or rubber insulating mat, and use tools with insulated handles when ser-

vicing the generator.

• Engine antifreeze is toxic to humans and animals. Clean up spills and

dispose of used engine antifreeze in accordance with local environmen-

tal regulations.

• Make sure all fasteners are secure and torqued properly.

4.6 Service Safety

Machine modifications

When servicing or maintaining the machine:

• Use only accessories/attachments that are approved by Wacker Neuson.

• Do not disable safety devices.

• Do not modify the machine without the express written approval of

Wacker Neuson.
